This converter allows you to convert joules per hour [J/h] to gigawatts [GW] or gigawatts [GW] to joules per hour [J/h]. Calculations are performed in both directions. The calculation result and the entered value are displayed with up to 20 decimal places for maximum accuracy.

1 joule per hour [J/h] ≈ 2.778 * 10-13 gigawatts [GW]1 gigawatt [GW] = 3.6 * 1012 joules per hour [J/h]

Convert joules per hour to gigawatts

There are two simple ways to convert joules per hour [J/h] to gigawatts [GW]. In the first calculation method, the value in joules per hour [J/h] is divided by 3.6 * 1012. The second method multiplies the value in joules per hour [J/h] by the rounded conversion factor of 2.778 * 10-13.

  • Gigawatts [GW] = joules per hour [J/h] ÷ (3.6 * 1012)
  • Gigawatts [GW] ≈ joules per hour [J/h] * 2.778 * 10-13

The calculation method with a rounded conversion value is more suitable for rough conversions from joules per hour [J/h] to gigawatts [GW], as the calculation result may contain rounding errors. Therefore, the variant with the exact conversion factor is more suitable.


Convert gigawatts to joules per hour

Converting gigawatts [GW] to joules per hour [J/h] is easy and can be done in two ways. The first method involves multiplication, whereby the value in gigawatts [GW] is multiplied by 3.6 * 1012. The second variant is a division. Here, the value in gigawatts [GW] is divided by the rounded conversion factor of 2.778 * 10-13.

  • Joules per hour [J/h] = gigawatts [GW] * 3.6 * 1012
  • Joules per hour [J/h] ≈ gigawatts [GW] ÷ (2.778 * 10-13)

The rounded conversion value can cause rounding errors, resulting in inaccurate calculation results. To ensure that the conversion from gigawatts [GW] to joules per hour [J/h] produces the most accurate calculation result possible, the conversion should be performed using the exact conversion factor.
